What the evidence says

Each claim has a specific scope. A source can support an observation while leaving its interpretation open.

  1. Reported observationSupported within stated scope

    The reported sample comprised 21 extreme debris-disc systems, combining observations of 16 systems with Webb and five from archival Spitzer data.[1]

    Scope: Reported sample and telescope allocation; not all young planetary systems.

    Limit: Institutional release inspected; underlying paper abstract/metadata cross-checked but full text and raw spectra remain uninspected.

  2. InterpretationTentative

    The authors interpret silica-rich debris as evidence consistent with energetic collisions between large planetary bodies.[1]

    Scope: Authors' interpretation of silica-rich spectra in a selected sample.

    Limit: Planetary impacts and impactor sizes are inferred from spectra and physical models. Collisions were not directly observed; mineralogy/age interpretation remains to be tested in larger samples.
